Micromodem Bare Board Systems

There are a variety of Micromodem configurations available. Configurations vary by power amplifier size, shape, and communication capability. The configuration required is dependent on the application. We can help you determine what hardware is most suitable for your application.

For simplicity the three primary configurations for a particular power amplifier form factor are shown here. Our other power amplifier designs can be found on the Micromodem Power Amplifier page. Any of of our available power amplifiers can be substituted for the one represented below.

Other configuration details are available upon request.Micromodem 2 Multi-Channel PSK Stack with Power Amplifier:

The Micromodem 2 Multi-RX PSK Stack with Power amplifier includes the following:

  • Micromodem 2 DSP
  • Micromodem Coprocessor
  • Micromodem Multi-Channel Analog Interface
  • Micromodem Power Amplifier

This configuration allows for the Micromodem to utilize a dedicated transducer to transmit and receive both FSK and PSK Micromodem signals. Additionally the Micromodem can interface to a 4 element RX spatial diversity array to receive Micromodem PSK communication signals. PSK Micromodem systems that utilize a 4 element spatial diversity array typically out perform single channel systems in the same environment.

Typical operational frequency bands for this form factor range from 8kHz to 30kHz depending on the transducer specified and the required source level requirements for the application.

Micromodem 2 Single-Channel PSK Stack with Power Amplifier:

The Micromodem 2 Single-RX PSK Stack with Power amplifier includes the following:

  • Micromodem 2 DSP
  • Micromodem Coprocessor
  • Micromodem Power Amplifier

This configuration allows for the Micromodem to utilize a dedicated transducer to transmit and receive both FSK and PSK Micromodem signals.

Typical operational frequency bands for this form factor range from 8kHz to 30kHz depending on the transducer specified and the required source level requirements for the application.

250035-ASM details mechanical dimensions, and included hardware, and connector locations.

Micromodem 2 FSK Stack with Power Amplifier:

This configuration allows for the Micromodem to utilize a dedicated transducer to transmit FSK and PSK Micromodem signals but can only receive FSK Micromodem signals. Future Micromodem 2 firmware updates may allow for native PSK support. Availability for native PSK functionality is pending.

Typical operational frequency bands for this form factor range from 8kHz to 30kHz depending on the transducer specified and the required source level requirements for the application.

250029-ASM details mechanical dimensions, and included hardware, and connector locations.

250029-SCH details a typical electrical integration of a Micromodem 2 FSK RFF Stack.

 


Micromodem 2 Multi-RX PS Stack with Power Amplifier and Off Board Magnetics:

The Micromodem 2 Multi-RX PSK Stack with Power amplifier includes the following:

  • Micromodem 2 DSP
  • Micromodem Coprocessor
  • Micromodem Multi-Channel Analog Interface
  • Micromodem Power Amplifier with Off Board Magnetics Module

This configuration allows for the Micromodem to utilize a dedicated transducer to transmit and receive both FSK and PSK Micromodem signals. Additionally the Micromodem can interface to a 4 element RX spatial diversity array to receive Micromodem PSK communication signals. PSK Micromodem systems that utilize a 4 element spatial diversity array typically out perform single channel systems in the same environment.

Typical operational frequency bands for this form factor range from 400Hz to 6kHz depending on the transducer specified and the required source level requirements for the application.

250046-ASM details mechanical dimensions, and included hardware, and connector locations.

250046-SCH details a typical electrical integration of a Micromodem 2 FSK RFF Stack.
